When you edit a page, there’s a Visibility tag in the right column. That tag has its own Edit link. Click that and then set Visibility to Public (default), Password Protected, or Private. If you Password Protect it, you get to choose one password that everybody will need to use to view the page.

Too darn easy.
I’d really prefer if each person could have their own username and password, but this is easy and will suffice…
I was looking for something more complex, never even considered that.
Thanks so much.
